Hello everyone, let's start the question.
00:03
In this question we are asked to write the mechanism for base catalyzed acid base, ketoinol, torsumerism for an aldehyde.
00:19
So if you start the mechanism, this is the structure which has three hydrogens depicted like this.
00:32
There is a presence of lone pairs, two lone pairs, an oxygen atom since it is present in a double one to carbon.
00:41
This one will shift here and because it is base catalyzed, not acid catalyze.
00:49
So this is the nucleophile which will abstract this hydrogen.
00:56
This is the keto form of the structure.
01:02
Now, the conversion of keto to in all form is less, whereas the in all form gets converted into keto form very rapidly as represented by these two arrows, as the forward arrow is quite less and reverse is fast.
01:23
So, we are going to draw the in all form for this, in which to this oxygen, one hydrogen will attach...
